Try not to worry about what other people are doing, if your child is having a tantrum in public. You'd like to think that most people have had experience of children and will have gone through that at some point.

You will see a glass test or tumbler test being performed on a sick child with a non-blanching rash. This will allow you to assess your child's rash.

About one or two babies in every thousand are born with a permanent hearing loss in one or both ears. Most of these babies are born into families with no history of hearing loss.

It's very important if your child has a medical condition to let your pediatrician know before you're traveling, and take his contact information with you, just in case.

The first thing you're going to need, of course, are diapers, wipes, a changing pad, and some diaper cream. Those are must-haves for any diaper bag.
